cabezon Scorpaenichthys marmoratus this cabezon was unusual with a lot of white coloration	a closer look at that cabezon Scorpaenichthys marmoratus	slug Flabellina iodinea a good look at its head, showing (from the front) its mouth (with scraping radula inside), its two long purple oral tentacles (sensory organs), its two reddish rhinophores with the white blazes (perhaps used for finding food and a mate), and its orange cerata (used for respiration and, in some nudibranchs, defense). I think the pores at mid-body are for access to reproductive organs.
painted greenling Oxylebius pictus	slug Hermissenda opalescens	scalyhead sculpin Artedius harringtoni not sure about this ID; it doesn't look like a painted greenling or a sarcastic fringehead
slug Flabellina trilineata	slug Flabellina trilineata showing its freshly laid eggs	brown cup coral Paracyathus stearnsi on blue encrusting sponge
